Title: Binarizing method for gradation image
Inventor: MURAYAMA MASAYOSHI
IPC: H04N1/40
Filed: 1989-05-08
Abstract: PURPOSE:To eliminate a blackish highlight part which is produced with use of a low image resolution storage by increasing a valid output image part each dot or every plural dots in accordance with an input level in order to obtain a binarized pseudo gradation image of high quality corresponding to an input signal having the gradation. CONSTITUTION:When the threshold value matrices 11 are arranged vertically and horizontally with no space secured among them, a threshold value data pattern of an area having the same size as the matrix formed around the apex of said matrix 11 is formed so as to be equal to the matrix 11. An input image is binarized with use of the matrix 11 and its output image is turned into a mesh image having a screen angle of 45 deg. which is used for printing of the black/ white photos in a newspaper, etc. The mesh are least conspicuous at the 45 deg. screen angle. As a result, the picture quality is improved.

Title: Receiver and receiving method
Inventor: MOMOSHIRO TOSHIHISA
IPC: H04L7/00
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To accurately reproduce a clock signal in an OFDM(orthogonal frequency division multiplexing) receiver. SOLUTION: I channel data and Q channel data are undergone differential demodulation by a differential demodulation circuit 503 and supplied to a ROM 512. The ROM 512 read inter-symbol phase fluctuation quantity that corresponds to differential demodulation data and supplies it to a gate circuit 514. The circuit 514 extracts only a component that corresponds to a pilot signal in input data and supplies it to a code inverting circuit 521 and a selector 522. The selector 522 selects an output of the circuit 514 when the frequency of a pilot signal is a positive value, selects an output of the circuit 521 in the case of a negative value and outputs it to an accumulative addition circuit 515. The circuit 515 accumulatively adds values that are outputted from the selector 522 over a symbol period and outputs an acquired value to a mean value circuit 516. The circuit 516 balances outputs of the circuit 515 and controls an oscillation frequency of a clock signal in accordance with an acquired value.

Title: Ultrasonic atomizer
Inventor: NAKAYAMA SHIYUUZOU
IPC: F23D11/34
Filed: 1978-09-18
Abstract: PURPOSE: To facilitate ultrasonic cleaning by forming water-proof structure, high frequency output from oscillator is magnetically coupled in a connector device to provide output.  
     CONSTITUTION: Ultrasonic wave is transmitted to atomized liquid fed from the tank 8 to the atomizing liquid bath 3 and causes fog from the surface. In this process, dirt and dust in the atomized liquid is piled up on the face of the vibrator 4 which must be removed. Cleaning such dirt is greatly facilitated by attaching the atomizing liquid bath 3 so that it can be free to be detached. The whole assembly can be made washable if the back surface of the vibrator is made water-proof. Such water-proof construction is easily realized if the connector unit 5 is formed to allow high frequency output from the oscillator 6 to magnetically couple to provide output. Such means further permits the atomizing liquid bath 3 and the body 2 to be easily connected and disconnected.

Title: Pile foundation structure
Inventor: WAKITA EIJI
IPC: E02D27/34
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To stably support a building even to a ground subsidence, reduce a pile load, and impart base isolating performance to a superstructure by dividing a building body into a foundation structure supported by the ground and the superstructure supported by a pile. SOLUTION: The lower part of a foundation structure 20 is buried in a recessed part G10 formed in a ground G, a hollow column 22 is arranged therein, and a superstructure 30 is supported by a pile 50 penetrating through the hollow column 22. A friction reducing material 60 such as asphalt is applied to the circumferential surface of the hollow column 22 penetrating part of the pile 50, and a viscous medium 70 is further filled therein. When a ground subsidence occurs, the superstructure 30 is supported by the pile 50 to keep its position, and the foundation structure 20 is subsided together with the ground and supported by a ground reaction F20. The horizontal vibration energy of the pile 50 is effectively absorbed by the viscous medium filled in the hollow column 22 and never transmitted to the superstructure 30.  Therefore, the ground reaction F20 is effectively utilized to reduce the pile load, and base isolating performance can be imparted to the superstructure 30.

Title: Schmitt circuit
Inventor: AMANO KAORI
IPC: H03K3/353
Filed: 1987-05-11
Abstract: PURPOSE:To remarkably reduce the fluctuation of a threshold voltage due to the manufacturing dispersion by adopting a bipolar transistor(TR) as an element deciding a threshold voltage and obtaining an optional threshold voltage through the setting of a base bias voltage. CONSTITUTION:The titled circuit consists of P-channel TRs 2-4, N-channel TRs 7-9, an NPN TR 1, a PNP TR 7, a resistor 5, bias voltages 11, 12, and a power supply 14. The threshold voltage is decided by the TRs 2, 6, 7 because the TR 3 is turned on with respect to a negative power supply (a negative terminal of the power supply 14) taken as the reference. Thus, by varying a base bias voltage of the TRs 1, 6, it is possible to vary the setting value of the threshold voltage. By combining the bipolar TRs in this way, even if the dispersion in the manufacture of an integrated circuit is large, the threshold voltage is easily set.
